Sorry if this is old news, I'm relatively new here, so still browsing through old threads. Although I bought my first detector over 20 years ago (Passport), I haven't used one in the past few years, so haven't really been keeping up with the technology until the past couple of months.
I came across the following chart from the archived stickys thread in the General forum, some of Mike B's results in the lab. I've been considering a Passport 9500i, so I found some of Mike B's results interesting when compared to the Guys Of Lidar test. Mike B's results are from May 07 (at least that's when they were posted here) and the GOL tests are from Aug 07, so they're relatively close in time.
The GOL test:
Guys of LIDAR - Radar Detector Test - August 2007
The 9500i in Mike B's chart is pretty close to the Bel 65 and the Passport 8500 X50in sensitivity. Most would say that's to be expected since they're all on the M4 platform. The RX65 and the X50 results in the GOL tests are pretty much consistent with Mike B's lab results relative to other detectors, however, in the GOL tests the 9500i they used runs neck in neck with the Valentines, and frequently ahead of the Bel STi. In Mike B's results, the STi and the Valentines show an advantage in sensitivity in most areas compared to the 9500i.
Anyone know if there some revision in the 9500i's software or hardware that was made mid-2007 to account for this?
Maybe the GOL 9500i was just a particularly hot unit and the results can be written off as a production variation, but the 9500i (in the GOL tests at least) comes off as pretty impressive.
